.410 Bore Shotshell Snap Cap / Dummy Rounds
Notes
- Should be printed with proper material & infill for strength, especially for the rim.
Models
- 410Bore_[2, 2.5, 3, 57_35mm]IN_Shell_Model_NoPrimerPocket.stl
- Has no primer pocket - Simplest file, No supports needed (Print with rim facing down)
- 410Bore_[2, 2.5, 3, 57_35mm]IN_Shell- Primer Pocket.stl
- Has primer rim pocket and primer pocket on the bottom. For some snap caps it can be useful to put some Silicone / rubber in that area to test for firing pin indentation.
- This will require some supports. It cannot be printed upside down because of the cartridge rim.
- ATI .410ga Rifled Slug 2.5 inch Shotgun Shell_NoPrimerPocket.stl
- Specific shell modeled on ATI .410GA 2.5" Rifled Shells - for function cycle testing in AR platforms.
4/22/23: Added two new STL for 2.5" rounds that are 2.5" style but are actually ~57.35mm length (For AR platforms)
4/28/23: Added a 2.5" Shell (57.4MM) modeled after ATI 2.5" Rifled Slug. Has taper at top (cycling for AR style needs this) - this model cycled/worked in an AR-15 lower. It's in the No Primer Pocket Section
